It’s not so simple as this. On-demand solar power involves higher cost for the storage than the panels themselves. Energy conversion machinery for grid feedback is also a cost sometimes commensurate to the cost of the panels (installation costs are also all over the place). The energy conversion costs could be reduced substantially by avoiding grid feedback in the first place, but then you’re talking about a new kind of electric grid in parallel with our own.

Storage, of course, is a fundamental part of EVs because they must cary the stored energy in batteries with them. Again, we find that batteries are more expensive than the energy itself.

Robocars could, as you touch on, provide some additional value capture by adjusting their behavior to match with grid demand times, as well as shouldering almost the entire task of grid stability management.
